SPECIFICATION forming part of Letters Patent No. 648,495, dated May 1, 1900.

. Serial No. 702,763. (No model.)

To @ZZ wiz/0m t may concern:

Be it known that I, ROBERT C. J ARvIs, a citizen of the United States of America, and a resident of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Chairs, of which the following is a specification, and which are fully illustrated in the accompan ying drawings, forming a part thereof.

The invention relates particularly to knockdown chairs, some. of its features, however, being adapted to chairs designed to continue in a set-up condition. Y

The objects of the invention are to provide a chair which may be readily dismembered, so as to be packed in a convenient form for carrying, and yet which .when set up will provide a comfortable seat, and to provide a spring supported swinging seat for such chairs or chai-rs of any style. These objects are accomplished in the construction hereinafter fully described, and which is illustrated in the accompanying drawings, in which- Figure I is a front elevation of a chair, the table being shown in dotted lines. Fig. 2 is av side elevation of the same. Fig. 3 is a detail side view, partly in section and partly in elevation. Fig. et is a detail front View of the lower ends of the front legs of the chair, being partly in section. Fig. 5 is a detail of one of the rear legs of the chair, partly in section. Fig. 6 is a front elevation of the panel of the back of the chair, its two main sections being separated. Fig. 7 is a side elevation of the same. Fig. 8 is a detail edge View of one of the main sections of this panel, showing its hinge. Fig. 9 is a plan view of the seat of the chair. Fig. 10 is an edge view of the same. Fig. IOLL is a detail of the seatshowing means for attaching the suspending-springs thereto.

The body of the chair comprises the front legs A A and rear legs A A', the adjacent legs being connected by means of spindles B, and at their upper ends the front and rear legs are connected by means of the arms O. The seat I) is swung from the arms O O by means of the coil-springs E, one at each corner of the seat. Extensions F F are provided for the rear legs A A to support the back of the chair, and a bow f connects the upper ends of these two extensions. Straight transverse spindles j" connect the two extensions F F and serve as means for supporting the panel G of the back.

The frame of the chair, with the exception ofthe arms O C, is composed of metal tubing. Each of the legs is preferably 'composed of three sections, the intermediate section, being the largest in diameter, receiving the upper and lower sections. The several sections are secured together by passing the rods of the spindles B through them. The spindles comprise tubes b of such length that they abut against the inner faces of the legs with which they coperate and rods b', which pass through the legs and to the ends of which are applied suitable nuts b2. The arms C O are each secured to the legs A/ in any suitable manner, as shown, by means of a bolt c, set into its end and projecting a sufficient distance, so that it may be passed through a suitable aperture in the leg A and receive a nut c. The forward end of each arm O is socketed to receive the front leg A, and a pin may be set transversely through the two members, as shown, to secure them together. Screw-eyes, as e, may be set into the under faces of the arm C, to which the springs E may be attached. I prefer to substitute for the simple form of screw-eye for supporting the rearward springs an eye e', having a stem for engaging the bolt c. The springs are preferably attached tothe seat by having their ends passed into suitable recesses, as shown in Fig. 10a, across each of which pass a bolt e2, the aperture within which the bolt plays being counter-bored to receive a coil-spring e3, which is arranged to hold the bolt to its seat, thereby aording a ready means for disconnecting the seat from the chair. The seat D is preferably of Wood and comprises a frame and a panel d and is divided into two halves which are connected by the hinges d', which flex downwardlythat is to say, so that the two sections of the seat may be closed together by having their outer edges thrown downward.

The extensions F of the legs A are shown as being composed of two sections, the lower one being about the same diameter as the intermediate sections of the legs, so that they will fit on the upper ends of the latter, the

upper and lower sections of the legs, so that IOO they will it in the lower sections of the extensions. The bowfis of still smaller diameter, so that it enters the upper ends of the extensions F.

The panel G of the back comprises four sections, being divided vertically and horizontally. The upper and lower members g g of each half of the'back are hinged together, so that when disconnected from the chair they fold by iiexing backwardly, and the two halves of the back thus formed are preferably secured together, when applied to the back, by means of the hooks H, secured to one of the sections and engaging suitable studs h set in the other. The tWo sections of the panel G are provided with hooks M for en gaging the spindles f.

It Will be seen that a chair constructed as shown and described may be readily sep- *l Witnesses:

travelers and pleasure-seekers, as it may be packedv into a very small ease.

I claim as my invention- 1. As an article of manufacture, a knockdown chair having its frameformed of de" folding seat having apertures for receiving 35 the eyes of the springs, and spring-seated bolts housed in suitable sockets in the seat and crossing the apertures for the springeyes, whereby the seat may be readily attached to and detached from the springs, E.
